It's interesting to read the variety of people's possible uses for a shotgun particularly those gearing for "inside the house use" say barricaded in a room.
I've grabbed & gone outside with a 12 gauge hundreds of times over the years. When the dogs talk, I listen
Usually it's small predators (mostly coyotes), sometimes it's a neighbors bull, once it was 3 youths, sometimes javelina, bobcats, lost hippies, every few years groups of feral dogs, or city people letting their dogs run free when they stop. There's about a zero percent chance of me using a 12 ga. inside the house, I've used one many times outside so my world revolves around that. I hike with one strapped to my ruck, based out of my house so weight is not an issue, I load extra weight in my ruck if it's too light.
OP would probably consider me absurd or Gecko 45 like, but ammo is my friend in my circumstances.
The only time I've called the cops was the 3 junior hoodlums and 2 deputies arrived well over an hour later, I think it was 1:45. So we're pretty much left to our own devices.
